The OP said he JUST got his device a month ago in his top post. It's not clear if it's a second hand device or not, but the fact that there are multiple programs installed that he apparently doesn't recognize would indicate it's probably a second-hand device. Given that, I simply stated it would be far easier to backup what little content he's personally put on it in the past month, and re-flash it, rather than try to diagnose and undo what someone else did to it before he owned it! That's not chafe, it's common sense.

As I already noted, there's a lot of IRQ and dss activity going on, which indicate a bad setting or possibly faulty hardware. (Kudos to Andrew_b: Yes, it could be an external component, like bad wifi point, or a bluetooth device like I mentioned earlier.) I put in the post above alternate things to check for or try if he's trying to avoid doing a reflash.

At no point did I say "the ops o(sic) recourse is a complete reflash". Please don't put words in my mouth, saying I said something when clearly I said no such thing. (That's called lying in my country...) Sad that you find the need to be-little my comments to cover for your suggesting useless "fixes" like telling someone that uninstalling a tutorial video or a non-active app installer will help with their battery usage.
